| 分析有水草水面、污水面、受热水面、盐水（卤水）面等特定水面类型的蒸发量，并与清水、淡水对照，求出蒸发比；还计算了太湖地区有水草水面和受热水面的蒸发模型，为确定湖泊的蒸发量提供一新途径；最后建议用水生植物的蒸腾规律来控制水面蒸发，调节水面温度。 |

| Abstract: |
| This paper reports results of study on the characteristics of evaporation from (water plant covered, polluted, hot salty, etc.) water surfaces and presents an equation on the amount of evaporation from various water surfaces including water surface with plants, intruded salt water surface, etc. New water surfaces such as polluted water surface and hot water surfaces appeared with economic development in recent years. These water surfaces have different regularities of evaporation Evaporation ratios of different kinds of water environment are listed in the following Table:
(For the table and equations please see the PDF file.)
where E, E0 are evaporation from water environment and from free freshwater surface; Ki is evaporation ratio of different kinds of water environment and Fi is its area. The factors affecting evaporation are analyzed singly in this paper although the factors are interrelated and mutually affect one another. Study on the combined effect of factors should be on the physicochemical characters of water, evapotranspiration from water surface with plants. relation between water and vapor heat exchange in water, etc. |
